Cardiovascular System Practice Exam
1. This heart condition is characterized by decreased cardiac output and tissue perfusion, which can lead to organ failure.
- A. Cardiogenic shock
- B. Myocardial infarction
- C. Endocarditis
- D. Pericarditis
Correct answer: A
Rationale: The correct answer is A: Cardiogenic shock. Cardiogenic shock is a severe condition characterized by the heart's inability to pump enough blood, leading to decreased cardiac output and tissue perfusion, which can result in organ failure. Choice B, Myocardial infarction, specifically refers to a blockage of blood flow to the heart muscle. Choices C and D, Endocarditis and Pericarditis, do not directly involve decreased cardiac output leading to organ failure, making them incorrect in the context of the symptoms described in the question.
2. What is a condition where the heart muscle becomes abnormally enlarged, thickened, or stiffened, often leading to heart failure?
- A. Cardiomyopathy
- B. Pericarditis
- C. Aortic stenosis
- D. Mitral valve prolapse
Correct answer: A
Rationale: Cardiomyopathy is the correct answer. It is a condition characterized by the abnormal enlargement, thickening, or stiffening of the heart muscle, which can lead to heart failure. Pericarditis (choice B) is inflammation of the pericardium, the sac surrounding the heart, not directly related to heart muscle enlargement. Aortic stenosis (choice C) is the narrowing of the aortic valve opening, affecting blood flow from the heart, but not directly related to heart muscle enlargement. Mitral valve prolapse (choice D) is a condition where the valve between the left atrium and left ventricle doesn't close properly, causing blood to leak backward, and is not directly related to heart muscle enlargement.
3. What is the buildup of plaque in the arteries that can lead to heart attack, stroke, and other cardiovascular diseases?
- A. Atherosclerosis
- B. Arteriosclerosis
- C. Hypertension
- D. Diabetes
Correct answer: A
Rationale: Atherosclerosis is the correct answer. It is the buildup of plaque in the arteries, leading to the narrowing of blood vessels, reduced blood flow, and an increased risk of heart attacks, strokes, and other cardiovascular diseases. Arteriosclerosis (choice B) refers to the hardening and thickening of arterial walls, while hypertension (choice C) is high blood pressure, and diabetes (choice D) is a metabolic disorder characterized by high blood sugar levels. Therefore, choices B, C, and D are incorrect in the context of the question.
4. The client on spironolactone should avoid which of the following?
- A. Foods high in potassium
- B. Foods high in sodium
- C. Foods high in calcium
- D. Foods high in chloride
Correct answer: A
Rationale: The correct answer is A: Foods high in potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and excrete sodium. Consuming foods high in potassium while on spironolactone can lead to an excess of potassium in the body, potentially causing hyperkalemia. Choices B, C, and D are incorrect because spironolactone does not directly interact with sodium, calcium, or chloride in a way that would require specific dietary restrictions related to these minerals.
5. The healthcare provider is monitoring a client receiving lidocaine IV. What side effect is the healthcare provider most concerned about?
- A. Severe headache
- B. Nausea and vomiting
- C. Seizures
- D. Tremors
Correct answer: C
Rationale: Seizures are the most concerning side effect of lidocaine IV administration due to its potential to indicate lidocaine toxicity, which can lead to serious complications such as cardiovascular collapse. Headache, nausea, and tremors are not typically associated with lidocaine IV and are less concerning compared to seizures in this context.
